Which mechanism enables holographic data storage using lasers?

💡 Explanation

Photochemical hole burning precisely alters spectral absorption, storing data bits, because laser light induces selective photochemical changes in the storage medium; therefore data is encoded, rather than relying on other nonlinear optical effects.
